Abstract

The utility model discloses a LED tube lamp, which comprises a lamp holder, a LED light source and a lamp cup, wherein the lamp cup is of a cover body with a opening; the inner wall of the lamp cup is coated with a glass sand layer; optimally, the inner wall of the glass sand layer is coated with a phosphor powder layer. The glass sand layer can effectively improve the diffusion rate of light ray, and the phosphor powder layer can soften the light ray reflected by the glass sand layer, thereby, the utility model has evener and softer irradiation effect.

Description

The LED Down lamp

Technical field

The utility model relates to the LED light fixture, relates in particular to a kind of LED cylinder lamp structure.

Background technology

LED (light emitting diode) is a kind of semiconductor solid luminescence device, when electric current can send the light of multiple color during by it.LED does not have that mercury is nontoxic, no electromagnetic pollution, no harm ray etc., is fit to very much make illuminating lamp.The LED lamp utilizes LED as the produced lighting of light source exactly.Compare with fluorescent lamp with incandescent lamp, it has, and power and energy saving, life-span are grown, are not generated heat, advantage such as shock-resistant, compare with fluorescent lamp, and the advantage of do not glimmer in addition, toggle speed is fast is considered as perfect light source of new generation by the photoelectricity industry.But existing LED lamp will be widely used in domestic lighting, also has following defective: the light of LED lamp is very dazzling, and promptly glare phenomenon is severe especially to the stimulation of eyes, and particularly the eye health influence to children is bigger.

The utility model content

The purpose of this utility model is at above-mentioned defective, and a kind of LED Down lamp with evenly softer radiation response is provided.

For achieving the above object, the utility model adopts following structure:

A kind of LED Down lamp comprises lamp bracket, LED lamp source and Lamp cup, and Lamp cup is the cover body that is provided with opening, and wherein, described Lamp cup inwall is covered with a glass layer of sand.

Wherein, described glass layer of sand inwall is covered with a phosphor powder layer.

Wherein, comprise radiator, this radiator is fixed between described lamp bracket and the described LED lamp source.

Wherein, comprise LGP, this LGP is fixed between described lamp bracket and the described Lamp cup.

The beneficial effects of the utility model are as follows:

Lamp cup inwall of the present utility model is covered with a glass layer of sand, described glass layer of sand inwall is covered with a phosphor powder layer, described glass layer of sand can effectively improve the diffusion rate of light, described phosphor powder layer can make the light that reflects from the glass layer of sand softer, as seen, the utlity model has evenly softer radiation response.

The 1-lamp bracket 11-support 111-first through hole 12-protecgulum 2-LED lamp source 21-LED lamp group 22-aluminium base 221-second through hole 3-Lamp cup 4-radiator 5-LGP 6-self-tapping screw 7-glass layer of sand 8-phosphor powder layer

The specific embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, present embodiment comprises lamp bracket 1, LED lamp source 2 and Lamp cup 3, lamp bracket 1 comprises support 11 and protecgulum 12, LED lamp source 2 comprises LED lamp group 21 and metal substrate, metal substrate can be aluminium base 22, LED lamp group 21 is packaged on the aluminium base 22, and present embodiment also comprises LGP 5 and is the radiator 4 of gear-like.

Support 11 is the shaped as frame of an end opening, support 11 central authorities are provided with two first through holes 111 that can match with self-tapping screw 6, radiator 4 is located at support 11 center bottom, self-tapping screw 6 can be passed first through hole 111 of support 11 and be engaged in the slot of radiator 4, radiator 4 is connected with support 11.Aluminium base 22 is located at radiator 4 bottoms, aluminium base 22 peripheries are provided with two second through holes 221 that can match with self-tapping screw 6, self-tapping screw 6 can be passed second through hole 221 of aluminium base 22 and be engaged in the slot of radiator 4, aluminium base 22 is connected with radiator 4.Lamp cup 3 is located at aluminium base 22 bottoms, and Lamp cup 3 is for being provided with the cover body of opening, and Lamp cup 3 inwalls are covered with a glass layer of sand 7, and glass layer of sand 7 inwalls are covered with a phosphor powder layer 8.The opening on Lamp cup 3 tops is less than the size of aluminium base 22 bottom surfaces, and LGP 5 is located at Lamp cup 3 bottoms, and LGP 5 upper surfaces are identical with Lamp cup 3 bottom end opening shapes.Protecgulum 12 is located at LGP 5 bottoms, and protecgulum 12 is the tubular structure of bottom flange, and protecgulum 12 tops are provided with the ring ladder that cooperates with LGP 5, and LGP 5 just in time is covered on the described ring ladder.

Select the support 11 of proper height and width, radiator 4, aluminium base 22, Lamp cup 3, LGP 5 can be arranged between support 11 and the protecgulum 12 compactly, by screw that support 11 is fixing with protecgulum 12 again, also the mode of available welding is fixing with protecgulum 12 with support 11, and radiator 4, aluminium base 22, Lamp cup 3 and LGP 5 are fixed between support 11 and the protecgulum 12.

The utility model is by covering glass layer of sand 7 and phosphor powder layer 8 successively at Lamp cup 3 inwalls, wherein, glass layer of sand 7 can effectively improve the diffusion rate of light, thereby obtains radiation response more uniformly, and phosphor powder layer 8 can make the light that reflects from glass layer of sand 7 softer.As seen, the utlity model has more all even softer radiation response.

The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
