The light can change dynamically to display different colors and patterns.

Description

A kind of Lawn lamp

1[technical field]

The utility model relates to a kind of Lawn lamp.

2[background technology]

People usually install some lamps and enrich lawn scenery at night on the lawn, make the lawn seem more charming in the night sky and beautify the lawn with this, increase the enjoyment of life at night.And the Lawn lamp that existing market is sold and used, its lamp housing is as a whole, install and remove extremely inconvenience when changing luminous tube, the Lights section that it adopts is an ordinary light source, for example bulb, shot-light etc., these light sources all adopt the alternating current of 220V, power is higher, relatively power consumption, and light does not have any variation simultaneously, relatively more dull, ornamental not strong.

3[summary of the invention]

The purpose of this utility model provides a kind of Lawn lamp, it is that lamp housing is made the several separate part, to reach the mounting or dismounting lamp and to change fluorescent tube purpose easily, adopt the LED luminous tube of a plurality of generation different colors of arranging by definite shape simultaneously, the LED luminous tube of these different colors takes turns luminous under the control of control circuit board or is simultaneously luminous, reaches better decorative effect.

The utility model is achieved by the following technical solution: it comprises housing parts, light source part and slotting ground part, housing parts comprises glass cover, shell and base, glass cover is nested in the top of shell, the bottom of shell is threaded with base top, between the boss of shell bottom and base, rubber ring is installed, the base bottom is connected with slotting ground part screw top, the Lights section comprises several luminous tubes, control circuit board and lamp socket, lamp socket is installed in the top of base, the LED luminous tube is installed on the control circuit board, and control circuit board is installed on the lamp socket by support bar.

Between the boss of above-mentioned described shell bottom and base rubber ring is installed.

Circuit part on the above-mentioned described control circuit board comprises time base circuit, addition register, drive circuit and power unit, power unit provides power supply for time base circuit, addition register, drive circuit, the output of time base circuit is connected with the input of addition register, the output of addition register is connected with the input of drive circuit, and the drive circuit output is connected with the LED luminous tube of many groups.

The LED luminous tube of above-mentioned described control circuit board is to be divided into a plurality of groups and by certain arranged in patterns.

The utility model compared with prior art has following advantage: it is that lamp housing is made the several separate part, to reach the mounting or dismounting lamp and to change fluorescent tube purpose easily, adopt the LED luminous tube of a plurality of generation different colors by the definite shape arranged in patterns simultaneously, the LED luminous tube of these different colors takes turns luminous under the control of control circuit board or is simultaneously luminous, reach better decorative effect, and the needed supply voltage of LED luminous tube is lower, power is little, power consumption is less, reaches the purpose of energy-saving durable.

The 5[specific embodiment]

As Fig. 1, shown in Figure 2, the utility model comprises housing parts, light source part and slotting ground part (8), it is characterized in that housing parts comprises glass cover (1), shell (2) and base (7), glass cover (1) is nested in the top of shell (2), the bottom of shell (2) is threaded with base (7) top, base (7) bottom is connected with slotting ground part (8) screw top, the Lights section comprises several LED luminous tubes (3), control circuit board (4) and lamp socket (5), lamp socket (5) is installed in the top of base (7), LED luminous tube (3) is installed on the control circuit board (4), and control circuit board (4) is installed on the lamp socket (5) by support bar (9).Circuit part on the control circuit board (4) comprises time base circuit (10), addition register (11), drive circuit (12) and power unit (13), power unit (13) is that time base circuit (10), addition register (11), drive circuit (12) provide power supply, the output of time base circuit (10) is connected with the input of addition register (11), the output of addition register (11) is connected with the input of drive circuit (12), and drive circuit (12) output is connected with the LED luminous tube (3) of many groups.The LED luminous tube (3) of control circuit board (4) is to be divided into a plurality of groups and by certain arranged in patterns.Between the boss (10) of shell (2) bottom and base (7) rubber ring (6) is installed, mainly plays preventing the into purpose of water.

Circuit part on the control circuit board of the present utility model (4) as shown in Figure 3, its principle is as follows: adopt time-base oscillation circuit HA17555 to do clock oscillation and reciprocation cycle clock control, make three kinds of color quartz spot lamps of loop control or LED reaches seven kinds of color effects of conversion with HEF4518 synchronous addition counter.Exchange 12V by D1～D4, the C1 rectification, filtering, give IC2 through the IC3 three-terminal voltage-stabilizing, IC2-HA17555 and peripheral cell composition square-wave pulse input to the 1st pin as the clock of IC1, IC1 begins counting, when first rising edge of a pulse arrives, the 3rd pin output high level, triode V3 conducting, relay K 1 adhesive, green one group of LED is that H1 sends green glow, through after a while, set between general 5～30 seconds, the 4th pin output high level, triode V4 turn-on relay K2 adhesive, one group of LED of ruddiness is that H2 sends ruddiness, can analyze thus, output the 3rd pin of IC1, the 4th pin, the 5th pin exports 100 successively, 010,110,001,101,011,111,000 o'clock, the lamp H1 of three groups of different colours, H2, H3 makes up the light that sends seven kinds of colors respectively successively, when IC1 the 3rd pin, the 4th pin, when the 5th pin is low level, V1 carries and ends, V2 turn-on relay K3 adhesive, blue led sends blue light, its effect is to eliminate counter the 3rd pin, the 4th pin, when the 5th pin is low level, and full optical phenomenon can not appear.
