Description

LED (light emitting diode) roll-up lamp convenient for adjusting length

Technical Field

the utility model belongs to a lighting apparatus especially relates to an use LED lamp and be used for precious light of easy-to-draw.

background

At present, LED lamps are widely used in landscape lighting, indoor lighting, commercial lighting and other occasions due to the advantages of energy conservation, environmental protection and the like.

the pop-top treasure is also called a poster frame and a display frame, is a standing propaganda poster, is commonly used in street passages with much popularity, assists a road show to promote activities, or is a temporary stand, and means that the pop-top treasure becomes a poster frame after being pulled open.

the main material of the roll screen is plastic or aluminum alloy. The roll is a telescopic column from the ground to the top, and a buckle is arranged on the top of the telescopic column.

When the roll up banner is displayed, the roll up poster needs to be illuminated sometimes to produce better effect, and the used illuminating lamp is called as a roll up banner lamp. Because the show environment of easy-to-draw precious and ambient lighting environment often have very big change, the illumination angle that needs the easy-to-draw precious lamp also has appropriate regulation nature and can conveniently adjust to throw light on to the easy-to-draw precious better, and should be convenient quick in the equipment, and require than higher to the heat conduction effect.

At present, the lamp post part of the LED easy-to-draw precious lamp is inserted on the adapters and the front clamps at two ends, when the length of the lamp post is fixed, the length of the whole LED easy-to-draw precious lamp is difficult to adjust by the structure, and the LED easy-to-draw precious lamp is not flexible to use.

SUMMERY OF THE UTILITY MODEL

The utility model provides a convenient precious lamp of LED easy-to-draw of adjusting length, its purpose is to solve the shortcoming that prior art exists, provides one kind and can adjust the precious lamp of LED easy-to-draw of length more nimble conveniently.

The utility model provides a technical scheme that its technical problem adopted is:

LED easy-to-draw precious lamp of convenient regulation length establishes the lamp shade of LED lamp pearl in having, and the lamp shade rear articulates there is the adapter, still has the preceding clamp of establishing LED drive power supply in having, and the both ends of lamp pole link firmly with adapter and preceding clamp respectively, have the electric wire and wear to establish and make LED lamp pearl and LED drive power supply electricity be connected in lamp shade, adapter, lamp pole, the preceding clamp, its characterized in that: the screw thread that the adapter tip set up and the top of lamp pole set up all the spiral shell establish in one go up coupling nut and make adapter and lamp pole be connected, and the screw thread that the preceding clamp tip set up and the bottom of lamp pole set up all the spiral shell establish in a lower coupling nut and make preceding clamp be connected with the lamp pole.

the technical scheme has the advantages that:

The utility model discloses a lamp pole both ends use the nut to combine with adapter and preceding clamp respectively as the transition connector, when the whole length of LED lamp need increase and shorten when in-service use, only need swivel nut to make the spiral shell of adapter, lamp pole, preceding clamp and nut establish partial length change, just can adjust LED easy-to-draw precious lamp length, and is very convenient.

drawings

the present invention will be further explained with reference to the drawings and examples.

FIG. 1 is a perspective exploded view of the present invention;

Fig. 2 is an external view of the present invention.

Detailed Description

The structure of the utility model is as shown in figure 1 and figure 2:

The lampshade is formed by inserting a lamp panel 4 with LED lamp beads into the top cover 1, inserting a reflective cup 5 and an acrylic surface cover 6 into the top cover 1 and fixing a left side cover 2 and a right side cover 3 on two sides of the top cover 1 by using self-tapping screws 19.

The adapter composed of a rotating shaft tower 8, a conical column 9 and a hollow iron pipe 10 is hinged on a connecting row 7 at the rear part of the top cover 1, and the end part of the hollow iron pipe 10 is provided with an external thread.

The upper cover 11 and the lower cover 16 are clamped and combined to form a front clamp, the LED driving power supply 14 is clamped in the front clamp, a triangle tail three-plug female socket 17 and a plug base male socket 18 which are connected with the LED driving power supply 14 are installed on the front clamp, a round head screw 12 is screwed with a copper column 15 in the front clamp, a hollow iron pipe 22 is clamped and fixed in the front clamp by an iron pipe fixing piece 13, and an external thread is arranged at the end part of the hollow iron pipe 22 extending out of the front clamp.

The lamp post 21 is a hollow iron pipe, and external threads are arranged at the top end and the bottom end of the lamp post.

The end of the hollow iron pipe 10 is provided with external threads and the top end of the lamp post 21 is provided with external threads which are all screwed in an upper connecting nut 20 in the form of M14 injection copper nut, so that the adapter is connected with the lamp post 21.

The external thread arranged at the end of the hollow iron pipe 22 and the thread arranged at the bottom end of the lamp post 21 are both screwed in a lower connecting nut 23 in the form of an M14 injection-molded copper nut, so that the front clamp is connected with the lamp post 21.

The electric wire is arranged in the lampshade, the adapter, the lamp post 21 and the front clamp in a penetrating mode to enable the LED lamp bead to be electrically connected with the LED driving power supply 14.

Like this, when needs adjust LED easy-to-draw precious lamp length according to actual conditions, have two regulation points, also rotate coupling nut 20 in, can adjust the top of hollow iron pipe 10 and lamp pole 21 respectively and go up the degree of depth in coupling nut 20, rotate coupling nut 23 down, can adjust the bottom of hollow iron pipe 22 and lamp pole 21 respectively and go up the degree of depth in coupling nut 23 down to reach the effect of conveniently adjusting the length of LED easy-to-draw precious lamp at any time and keeping lamp pole 10 and adapter and the being connected of preceding clamp simultaneously.

compared with the common light source, the novel LED light source has the following advantages:

1. Voltage: input voltage: 3-35VDC, constant current 350mA, can string 10 lamps at most, can use safely, conveniently, flexibly between 100 and 240V according to different user's demands;

2. Efficiency: the consumed energy is reduced by 80 percent compared with an incandescent lamp with the same luminous efficiency;

3. Applicability: widely, each unit LED die is 79mm rectangle, so that the LED die can be prepared into devices with various shapes and is suitable for variable environments;

4. Stability: 5 ten thousand hours, the light decay is 30 percent of the initial light decay;

5. response time: the response time of an incandescent lamp is in millisecond level, and the response time of an LED lamp is in nanosecond level;

6. and (3) environmental protection: no harmful metal mercury and no alternating current flash frequency;

7. color: the color temperature range is wide in 2700-;

The LED is a solid light-emitting device, is not easy to break and is convenient to transport and store;

9, the LED is a cold light source and does not generate high-temperature heat radiation to the outside;

The LED as the light source has the advantages of three aspects: energy saving, environmental protection and long service life.
